1.- Telefónica prueba VoLTE y demuestra integración de WiFi a la red.
Telefónica realizó, en el marco del Mobile World Congress de Barcelona, una demostración de la
integración entre la red móvil y Wi-Fi. La nueva tecnología permitiría cambiar de 3G o LTE a Wi-Fi de
manera imperceptible para el usuario y sin perder cobertura, explicó la compañía. Ello permite resolver el
problema de congestionamiento de las redes móviles y la falta de cobertura en las zonas con una alta
densidad de tráfico.
Durante la exposición, la empresa realizó además una prueba de servicios de voz sobre LTE (VoLTE).
La demostración se realizó en la banda de 2,6 GHz y con equipos Ericsson.
Telefónica señaló que el servicio de voz sobre LTE supone un 40 por ciento de mejora en la calidad de
voz y logra establecer una conexión 20 veces más rápida que una llamada 3G. Además, permite
combinarse con servicios de voz de alta definición, ubicación y Rich Communication Suit (RCS).
Asimismo, afirmó que la solución permite priorizar unas secuencias de datos sobre otras, ofreciendo un
servicio de alta calidad continuo y destacó que VoLTE emplea una única solución de radio en el
dispositivo del cliente, permitiendo mantener las llamadas sin interrupciones cuando un cliente pasa de
una zona de cobertura LTE a otra sin ella.

2.- Penetration loss in LTE.
Penetration loss in LTE indicates the fading of radio signals from an indoor terminal to a base station due
to obstruction by a building. For an indoor receiver to maintain normal communications, the signal must
be sufficiently strong. The indoor receiver obtains radio signals in the following scenarios:

2. fam’s teleco news (Año3-Nº12/Marzo 2013) 2/12
• The indoor receiver obtains signals from an outdoor transmitter.
• The transmitter and receiver are located in a same building. See Figure below
The link budget is only concerned with the scenario in which an outdoor transmitter is used and the
signals penetrate only one wall.
The propagation modes of electromagnetic waves are as follows: direct radiation, inverse radiation,
diffraction, penetration, and scattering.
In areas where no indoor distributed system is deployed, electromagnetic wave signals are obtained
through diffraction and scattering. Therefore, the indoor Penetration loss in LTE is related to the incident
angle, building materials, terrain, and working frequency. Table below lists the penetration losses
associated with typical buildings.
Typical building penetration losses
In the link budget, Penetration loss in LTE values depend on the coverage scenario. Therefore, coverage
target areas are classified into densely populated urban areas, common urban areas, suburban areas,
rural areas, and highways. Table below lists the area classification principles.
Principles for classifying coverage scenarios
The building Penetration loss in LTE ranges from 5 dB to 40 dB. In link budget, if no actual test data in the
target area is available, an assumed Penetration loss in LTE value must be used. The final assumption is
also highly dependent on local customer requirement.
For example in sophisticated Asian Metropolis like Hong Kong, Singapore and Shanghai, the indoor
coverage expectation will be very high, hence requiring a high Penetration loss in LTE provisioning. On
the other hand, in less developed market such as Africa and Latin America, customer expectation is lower
so the Penetration loss in LTE requirement can be reduced to reduce overall cost involved.
During network planning, if no actual field testing data is available, refer to the Penetration loss in LTE
values listed in Table below.

3.- Antenna Implants- Possible Future Trends.
Over the past two decades, the world has been able to benefit from its significant wealth in knowledge
relating to telecommunications engineering. During this time, there has been an exponential growth in the
field of mobile communications, proving beyond doubt that people love to talk. Coincident with this
success there has been a massive increase in healthcare provision in the world combined with an
associated revolution in how treatment is offered to the patient. The simplicity and utility of technologies
like Global System for Mobile Communications (GSM) with voice, data, 3G with streaming video and 4G
with its superior resource allocation all offer much to healthcare, particularly for non-secure medical
telemetry. Discussed here is the future concept of 4G systems implanted into the body with bidirectional
link to the cellular network. This is different from current systems that communicate with implanted
devices over short range links (<410 m).

Given the right safeguards for implanted mobile phone technology, it would for example be possible to
measure the properties of a heart attack in real time and perhaps monitor the effects of treatment
subsequent to the event, whilst allowing the patient freedom of movement. What would be needed would
be a system that could be implanted into a patient for short periods of time (perhaps several weeks) that
could be used to transmit data out of the body and to a medical expert. In this context such a system
would use data rather than voice, be non-real time with low isochronous application usage.
What is envisaged might be low SAR (Specific Absorption Rate) flexible antennas just beneath the skin
surface for use with cellular systems and their vast networks of base stations. Such a system would
comprise a small telecommunications module with integrated micro controller and power supply attached
by cable to an antenna. The module, its battery and its associated sensors would lie inside the body. To
minimize SAR the antenna would lie as close to the outside of the body as practical but not outside the
skin. The system would be encapsulated and screened to reduce energy interactions with tissue. From
the point of view of avoiding infection the proposal to have the whole system inside the body’s protective
skin is of clear benefit. By not breaching the skin complications arising from infection; hygiene and painful
snagging would be avoided. Furthermore such in-body systems would be invisible to other people and
may allow patients an extended freedom of movement and much more privacy. All of the components
except the antenna are state-of-the-art. In considering the size of such antennas we are helped a great

deal by the permittivity of the surrounding tissue which is generally high. Therefore, such antennas would
tend to be much smaller than their free-space counterparts (for example about 25mm long for a half wave
dipole at 900 MHz).
It can be shown, for example with LTE wireless communications, that it would not currently be a problem
sending 4G signals to a modem implanted inside a body cavity. However, because of the very strict
legacy limits related to medical implants, the tricky part of such a system would be how to get 4G signals
out of the body to a base station without exceeding SAR limits within the body. For a mobile handset
power levels from a handset are limited to 2 Watts but are typically around 0.6 Watts split across several
channels. However for medical implants the limit is 25 micro-Watts.
The standards germane to this discussion are the Medical Device Radiocommunications Service
(MedRadio) and the Wireless Medical Telemetry Service (WMTS). MedRadio has a spectrum between
401 and 457 MHz. The more common devices realized have been implanted cardiac pacemakers and
defibrillators, and neuromuscular stimulators for physical mobility. WMTS has spectrum at around 0.6
GHz and 1.4 GHz and has been used for sending data about such things as pulse and respiration rates to
close in receiving stations. A typical application would be a cardiac monitor wirelessly linked to a nurse’s
station for post operative care.
The ability to communicate with an implant over a high bandwidth link would facilitate many new
applications and enhance existing applications such as pacemakers, implantable cardioverter
defibrillators, neuro-stimulators, hearing aids, robotic prostheses, artificial eyes, brain pacemakers to
control Parkinsons disease, monitoring of blood glucose levels for diabetic patients, stimulation and
recording of brain and muscle activity, swallowable pills for traversing the gastrointestinal tract and
implantable drug delivery systems.
Implanted medical devices save lives, increase the quality of the user’s life, reduce the number of trips a
patient has to make to a hospital and save billions of dollars in hospital beds, resources and doctors’ time.
Lifesaving implants such as cardiac pacemakers, neuro-stimulators and pumps, have now become
routine and do not attract the negative media attention that normally follows attempts to create so
calledbionic people. The cardiac pacemakers and defibrillators have grown into a multi-billion pound
industry since the first implanted pacemaker in 1958. As implanted antennas are aimed at the same
market, improving the quality of life of severely ill patients or others who are at high risk of illness, it is
expected that it will be well received by both the medical community and patients alike.
After all, antennas are implanted inside the human body as a method of treating tumors using
hyperthermia. Previously, battery power has been a limiting factor. A typical pacemaker uses less than
10mW and the battery lasts 10 years. However, a long range medical biotelemetry system consisting of a
sensor(s), a battery, a 4G communications module and a low power subcutaneous antenna may only
need to be in place for a few weeks.

During the phase of preliminary acceptance before commercial launch, KPIs will be derived from the drive
test analysis and stationary measurements, and this analysis and measurement are on the basis of
cluster which constitutes a group of sites (20-40 sites).
Statistics KPIs are not proposed and measured at this stage as the traffic is insufficient, statistics will not
eligible statistical result without enough samples.
After on-going optimization while the traffic keeps increasing after commercial launch, the final
acceptance of the whole network performance on the basis of statistics will be implemented. However,
the KPI values of statistics probably might not be same with those in drive test due to different
calculations and considerations.
LTE Service KPIs and LTE Network KPIs
The Field Test KPIs into two categories: LTE Service KPIs and LTE Network KPIs.
Service KPIs are the KPIs that are not subject to be effected by cluster tuning and optimization
activities, mainly determined by product performance, configuration and parameter setting, e.g. ping
delay, throughput, etc. I recommend that only one cluster (named pilot cluster) is selected for the
evaluation and acceptance for the Service KPIs, no necessary for repeating the measurement in all
clusters Based on the above reasons, the Service KPIs’ test is suggested to be performed by Stationary
Test (ST) in the area with good RF conditions and close to the cell in order to eliminate the affect of poor
RF or non-equipment factor and the test is proposed to be implemented under the condition of one
serving cell.
LTE Network KPIs , such as Call setup success rate, Call Drop Rate, Handover Success Rate, which is
determined by the radio network environment, planning and optimization capabilities, should be
performed on the Drive Test (DT) routes in rollout clusters.

5.- Carrier Aggregation in LTE-Advanced – whitepaper.
In order to achieve up 1 Gbps peak data rate in future IMT-Advanced mobile systems, Carrier
Aggregation concept has been introduced by the 3GPP in its new LTE-Advanced standards (3GPP
Release 10 onwards). Carrier Aggregation is aimed to support very high data rate transmissions over
wide frequency bandwidth (e.g. up to 100MHz). This paper gives an overview o Carrier Aggregation,
including its types, cell configurations, its need and benefits. This paper also discusses in brief the major
functional changes required in PHY, MAC and RRC or Carrier Aggregation.

4.- LTE KPI Measurement Methodology and Acceptance Procedure.
Here I write in simple word on LTE KPI Measurement Methodology and its Acceptance Procedure. As it’s
for only at network start up stage and now a day worldwide so many operator starts to launch LTE and so
this is the way for them to check of KPI in LTE
LTE KPI Measurement Methodology
The KPIs are formulated to measure the network performance in terms of Accessibility, Integrity, Mobility,
Retainability, and Subscriber perceived quality.
LTE KPIs are mainly classified into 5 classes, which are, Accessibility, Retainability, Mobility, Latency,
and Integrity. The KPI architecture is shown in the following figure.
The above KPI classification fully considers the customer experience and focuses on the Quality of
Experience, providing a wide range of network KPIs to reflect network factors that are relative to the
service quality, using industry standards as reference to define network counters and KPIs.
LTE KPI Acceptance Procedure
LTE network KPI acceptance procedure for the two phases, preliminary acceptance and final acceptance,
are recommended as shown above.
